2.4 Setting Jumpers

You may configure your card to match the needs of your application by

setting jumpers. A jumper is a metal bridge used to close an electric cir-

cuit. It consists of two metal pins and a small metal clip (often protected

by a plastic cover) that slides over the pins to connect them. To “close” a

jumper, you connect the pins with the clip. To “open” a jumper, you

remove the clip. Sometimes a jumper will have three pins, labeled 1, 2

and 3. In this case you would connect either pins 1 and 2, or 2 and 3.

The jumper settings are schematically depicted in this manual as follows:.

A pair of needle-nose pliers may be helpful when working with jumpers.
